Seven people were wounded in a knife attack in the Russian city of Surgut and the man, who apparently stabbed passers-by on the street at random, was shot dead by police.
State-owned RIA Novosti news agency reports that the injured people have been taken to hospital, where two are in a critical condition.
Russia’s Investigations Committee said it had identified the attacker and was checking his psychological history. The attacker was a local resident born in 1994. So far, no motive has been established yet.
